It can also extend to timetable/exams/test memory, where one would constantly remind you of the class(or tests/exams) that you will be having, thinking that for some unknown reason, you, the person whom the timetable is specifically for, would not know what class or important sac you might have. And then to complete the retardation process, they would comment on something else entirely unrelated. e.g. weather.
